SPECIFICATION forming part of Letters E'atent No. 491,219, dated February '7, 1893.

Application filed June 7, 1892. Serial No. 435,891. No model.) Patented in fiwitzerland January 20, 1892, K0. 4.4.87.

To all whens it may concern:

Be it known that 1, PAUL LOOHMANN, a subject of the King of Saxon y, Germany, and a resident of the city of Gohlis, nearLeipsic, in the German Empire, have invented a certain new and nsefnl Governor for Regulating the Speed of Spring Driving Mechanism, (for which I have obtained a patent in the Republic of Switzerland, No. 4,487, hearing date January 20, 1892,) of which the following is a specification.

My invention relates to a governor for reg ulatingthe speed of springdrivingmechanism.

The object of the invention is to regulate automatically the speed of the driving mechanism b y means of spring air vanes or fliers which present a larger or smaller surface to the pressure of the air according to the increase or decrease of the speed of the driving mechanism. I attain this object inthe manner shown in the accompanying drawings in which Figure l is a sectional end view of the apparatus, the section being taken through line Jew-i3 of Fig. 2. Fig. 2 is a view of the governor and driving mechanism.

T is the driving mechanism. a the regulator spindle carried in bearings Z), Z) and driven by driving mechanism T.

c, c, are arms fixed by their boss (Z on spindie a to which arms, spring vanes f, f, are fixed so as to he diametrically opposite each other. These latter are made of a springing or yielding material and are curved or bent round at their free ends.

The governor Works in the following manof the radius of the circle which they describe.

Thus, the surface of the vanes exposed to the pressure of the air is increased as also is the resistance to their rotation so that the speed of the driving mechanism is lessened and the vanes return to their original curved or bent; form. In this Way the speed of the driving mechanism is automatically regulated and kept steady. The arms 0, c prevent the vanes from turning too far backward when the speed of the driving mechanism is very fast.

Having now described my invention, What I claim as new and desire to secure by Letters Patent is:-

A governor for driving mechanism comprising a spindle resilient vanes or fliers fixed diametrically opposite each other on said spindle, the free ends of said vanes being curved orbent, for the purpose specified substantially as described and shown.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
